Study Summary
Behavior modification programs hold promise for increasing levels of physical activity (PA) for individuals who are insufficiently active. However, existing interventions, which typically prescribe uniform PA goals across participants, are limited by their insensitivity to changing individual needs and circumstances over time. An alternative approach is to continuously adjust goal difficulty to match fluctuations in individual performance, or adaptive goal-setting (AGS), which evidence suggests may more effective for increasing PA than non-adaptive approaches. Still, no prior studies have examined the psychological mechanisms targeted by AGS, which limits the ability to further refine and disseminate this technique. In this exploratory study, several candidate mechanisms of AGS (expectancy beliefs about goals, perceived value of goals, affective appraisal of goals, implicit attitudes towards exercise) will be examined. Adult participants interested in increasing their level of physical activity (N = 36) will be randomized to receive 6 weeks of either adaptive goal-setting (AGS) or non-adaptive, static goal-setting (SGS) as part of a remote, low-intensity PA intervention. The primary aim of the study will be to evaluate the hypothesis that AGS, as compared to SGS, results in greater increases over time to four hypothesized psychological mechanisms. The secondary aim will be to evaluate whether post-intervention increases to any among these three mechanisms mediate the relationship between intervention type (AGS vs. SGS) and increases to PA over the course of the intervention.
Primary Outcome
Expectations about one's own ability to achieve physical activity goals will be assessed weekly using a single Likert scale derived from prior research on Expectancy-Values Theories (EVT) of achievement motivation. Responses on the scale will range from 1-5, with higher values representing higher expectations about one's ability to achieve daily activity goals.
